[POWERPC] Removed dead code related to PCI on ppc32
There are no in kernel users of any off these functions and some of
them were not even EXPORT_SYMBOL:
- pci_bus_io_base()
- pci_bus_io_base_phys()
- pci_bus_mem_base_phys()
- pci_resource_to_bus()
- phys_to_bus()
- pci_phys_to_bus()
- pci_bus_to_phys()
- pci_init_resource()
- resource_fixup()
